To all whom t may concern.'

Be it known that I, SAUL SHALER, a citizen of the United States, and aresident of the city of New York, borough of the Bronx, in the county ofBronx and State of New York, have invented a new and ImprovedCombination-Padlock, of which the following is a full, clear, and exactdescription.

This invention relates to pad locks and `has particular reference tocombination locks or such as may be manipulated without idmong theobjects of the invention is to provide a pad lock having a frame orbody, a removable shackle and a plurality of finger operated tumblersconstituting the means for locking the shackle in the body, saidtumblers being provided with index characters serving to establish theproper combination whereby the shackle may be removed when the tumblersare set in a predetermined position.

With the foregoing and other objects in view the invention consists inthe arrangement and combination of parts hereinafter described andclaimed, and while the invention is not restricted to the exact detailsof construction disclosed or suggested herein, still for the purpose ofillustrating a practical embodiment thereof reference is had to theaccompanying drawings, in which like reference characters designate thesame parts in the several views, and in which- Figure 1 is a sideelevation of my improved lock.

Fig. 2 is a vertical section of the same.

Fig. 3 is a perspective view of one of the heads.

Fig, 4 is a plan view of one of the bod plates; and y Fig. 5 is ahorizontal sectional detail on the line 5-5 of Fig. 2.

Referring` n'ow more specifically to the drawings I show my improvedlock as comprising a body 10 including right and left heads 11 and 12connected by means of any suitable upper and lower plates 13 and 14.-respectively, adapted to be rigidly secured to the heads by any suitablemeans.

The heads may be made of any suitable metal or its equivalent and aretubular each having a vertical bore 17 of any suitable size or form incross section being indicated as rectangular. The inner Wall 18 of eachhead or the wall constituting the face directed toward the opposite headis preferably flat and smooth, while the opposite or outside wall 19thereof is rounded although an)1 other form may be substituted for thesenncylindrical surface 19. Said inner wall 18 is provided with a pairof horizontal drill holes 20, the axes of which are in horizontalalinement with the corresponding holes of the opposite head. These holesare materially larger in diameter than the Width of the bores 17.

The bottom plate 14 is preferably solid or imperforate, while the upperplate 13 is provided with slots or holes 21 re 'stering with the upperends of the bores 1 and of the same size and form.

The shackle 22 comprises a loop or bail 23 and a pair of parallel shanksor legs 24. The form or cross section of the Shanks is substantially thesame as that of the slots 21 and bores 17 into which the Shanks areadapted to be projected for locking the shackle in the body. The bailportion of the shackle is provided with shoulders 25 or equivalent meansto limit the movement of the Shanks into the body heads. When theshackle is inserted into the body and the shoulders 25 impinge againstthe upper plate 13, notches 26 formed along the inner edges of theshanks 24 lie in registry with the holes 20, the vertical dimension orlength of the notches being the same as the diameter of the holes 20.

The space between the upper and lower plates 13 and 14.- andhorizontally between the two heads 11 and 12 is substantially filled bymeans of a plurality of pairs of tumblers 27 each of which comprises apreferably cylindrical portion, the inner end of which may be knurled at27 while at its outer end each tumbler has a central axial trunnion 28fitted into a hole 20. Thus each of the tumblers at its trunnion hasdlrect bearing in one of the heads, while at its end adjacent to thealined tumbler of the same pair has a dowel connection 29 with the otheralined tumbler. The dowel 29 is long enough to constitute a substantialsupport for the middle or adjacent end portions of each pair oftumblers. The dowel may be rigidly connected to one of the tumblers andhave loose engagement only wlth the other tumbler, or for convenience inassemblagethe dow'el .may have 4,m0.vable conneci vvidthof whichissubstantially the .same asy the thickness Aolf the Shanks; jlfhe lengthof eachof-the kerfs 31 is parallelfto the Shanks and hence perpendicularto the axis .of ithe tumblers. s

- F rom the foregoing .specific description ,of

the .mechanism .its ymode A:of operation wiflljbe appreciated it .isthought .from the following' summary: Each tumblervis :provided -withindex characters 32 represented as .the `digit numerals, although theymight be glettersor numbers of a higher order. These index characters.have reference .to pointers 33 formed on one sideof the Aheads oppositethe several tumblers.-v :The `index characters are formed on thetumblers 4in vany `desired relation to the kerfs whereby any.-dGSIBdxQOm.- bination of the index charactersl may be yprovided `forAany individual lock. When the prescribed characters `of a lock areadjusted.'

' inregistry with the pointers '33 all of the kerfswill-lie inthe 'sameplane, namely, the plane of the shackle shanks, thus setting theshacklefree to be ldrawn'from the fbody. VVlhen, however, anyone or moreof; the turn.-

1 1 blers .are turned slightly` fromfthis ,opening position the shacklewill be locked from removal ldue to the fact that least 4O'Ilno'f theshoulders 3.4: justbeglow the trunnions will strike against thecylindrical surface of i any trunnions tur-ned -rLOm .the aQresaidopening position.V Thus it will be seen that the shackle may be `easilylocked from re, moval and the Opening 0f the lock. may easily be eectedby any one-familiar with thecombina'tion of the particular lock. y Forany I one unfamiliar with. the combination the :task of opening the lockis practically hopeless. .l y The dei/ice is simple and cheap Ofstruction easy .0f manrulatsn and Strong and reliable iny practice.Eurthermgre it is not liable to get cut 0f order andannot fail toprovidefor the; direct removal; 0f' the shackle when the Prflper' combinationis observed. i vf The kerfs 31 be formed ill the ends ofthe trunnonjs 28lin any desired relation to the axes of the trunnions, but nreferably Iarrange @he wall-sottile kerfs parallel-te said axes.- andi slightly on?centerr as indicated in .exaggerated (leeres-l br they centrallyy drawndot and @flge 3 and In other words while thekrfs-ar'e all adapt* ed tooccupy thesame vertical plane and the shanks 24 of the shackle likewiselie in the ,Same plane it follows that the ,holes 2l .and `,tlie bores17 'must'fbe similarly oset from 'the central stri,1c-tionit5 ollowsthat there can be but one lane of the lock. By this conopening positionor adjustment of the several. tumblers 27. In other words yif the kerfswere central of the tumblers' there might be two different openingpositions or adjustments of the tumblers, one position being the oneintended `and the kother being the one 180 .degreesgremote therefrom.
